Sexual dimorphism as a facilitator of worker caste evolution in ants.

Ant societies are primarily composed of females, whereby labor is divided into reproductive, or queen, and non-reproductive, or worker, castes. Workers and reproductive queens can differ greatly in behavior, longevity, physiology, and morphology, but queen-worker differences are usually modest relative to the differences in males. Males are short-lived, typically do not provide the colony with labor, often look like a different species, and only occur seasonally.

"Where do I even start?" Recommendations for faculty diversifying syllabi in ecology, evolution, and the life sciences.

Diversifying curricula is of increasing interest in higher education, including in ecology and evolution and allied fields. Yet, many educators may not know where to start. Here we provide a framework for meeting standard curriculum goals while enacting anti-racist and anti-colonial syllabi that is grounded in the development of a sustainable network of educators.
